I recently logged three new stations on a frequency (1070 kc) that was previously unusable due to the proximity of a 50,000 watt station (WTIC), that is, its proximity of operating frequency (1080) and proximity of distance between it and my location (12 miles).
My success on 1070 is due to a new radio: C.Crane's new CC Skywave AM-FM-SW-WX-Air portable receiver that my sister gifted to me on Christmas. I have been so impressed with its capabilities on AM that I have not spent much time on its other bands, but I have noticed that it's sensitivity and selectivity on the FM band is top-notch and probably the best receiver I own in that regard.
Getting back to 1070... during the past week or so, I have concentrated on that frequency trying to catch another new entry for the log (so far I logged CHOK, WINA and WKOK, 488, 384 and 208 miles away, respectively ). I can still hear some WTIC on 1070, but I can null it out by positioning the CC Skywave 90° away from their transmitter site. That position puts WINA in the null (gray on the map) along with WTIC, while CHOK and WKOK fall somewhere in between the null and the sweet spot (green on the map).
By the way, I have the CC Skywave's bandwidth set to 2 kc for AM band DXing, which I find works well for extracting intelligence from weak signals with this radio (bandwidths from 1 to 6 kc in 1 kc steps are selectable).
The last two nights at around 0000 UTC, I heard voices and music occasionally pop up through the noise, but the signal(s) were not strong enough nor long enough to extract any intelligence.
I will keep on trying and keep you posted.
